Seco Precimaster Plus provides accuracy
Seco’s new generation Precimaster Plus modular, indexable-head reaming system provides accuracy and part processing versatility. Through a selection of various reamer shanks and heads, users can accommodate a variety of hole sizes and workpiece materials with fewer required tools. Additionally, new system design enhancements boost reaming speed, precision and repeatability for overall better production. With the system, industries such as aerospace and automotive gain extreme process stability and dependability paired with the lowest cost per part.
Precimaster Plus now uses solid-carbide disposable heads up to diameter 32 mm, coated and uncoated, in various diameters that mount to a standard range of shanks. As opposed to traditional brazed-tip technology, solid-carbide heads allow for an increased number of cutting teeth on the same head diameters for faster feed rate capability. Solid carbide also extends tool life, delivers increased stability for tougher materials and makes for a more cost-effective system.
A new Precimaster Plus patented high-precision connection ensures reamer head exchanges are fast and easy with repositioning repeatability and run out of under 3 microns. The new connection handles much higher levels of transmissible driving torque due to its special three vertical- drive-pin design. Internal axial clamping forces draw heads up and into system shanks, creating a strong and secure interface. Users gain the confidence and dependability to run any reamer head with any shank and for any material.
For chip control and management, Precimaster Plus reamer shanks can apply different types of flushing for both blind and through holes. Tool body coolant outlets in the front force chips up along head flutes and out of blind holes, while standard through-tool coolant blasts chips forward and away from the tool for efficient through-hole reaming.
